Separate tp: Mathematical Collections and Translations: the Second Tome. The Second Part;... By Thomas Salusbury, Esq. London, William Leybourne, MDCLXI. (with list of the 4 parts contained within, the first two also having their own tps); errata for Part II facing tp, [xii], 118 numbered pp, [v]. Should be "First Tome, Second Part."

There are a few errors in the typesetting of this volume, but all pages are present. Pages 70-75 numbered 70-71-7222-74-74-75; page 290 with "274" on verso of p. 289; pages 306 - 230 - 308; page 354 is set as 345; page 253 should be Dialogue III, not II, in header; page 389 with Dialogue III in header, even though it is in IV; and in second part pages 14-17-16-17.

Throughout, on various title pages, there is the typical variation in spelling of Salusbury/Salusburie and Leybourne/Leybourn.

This was the first translation of Galileo's work and was very influential in the English-speaking world. He set up his argument as a discussion between a proponent of Copernicus' model of the solar system/universe (Salviati), a follower of Ptolemy and Aristotle (Simplicio - likely also a play on words, implying simple-minded), and a neutral intelligent layman (Sagredo), who becomes convinced of the correctness of the Copernican view as the discussions continue over four days.

The discussion touches on many topics other than astronomy, both as part of the main debate and also as examples of what Galileo considers good science. He also attempted to use tides as a direct argument for the Earth's motion, an argument that did not work as well as Galileo had hoped, but seemingly explains the addition of the second part of the tome, "Of the Mensuration of Running Waters."

This part was written by Benedetto Antonio Castelli (1578-1643), a student, friend and supporter of Galileo, and, later, teacher to his son. Castelli was a Benedictine monk, as the first name indicates, and also a friend of Pope Urban's. Yet, Castelli was never arrested for heresy, and, indeed, became abbot of the monastery at Monte Cassino, yet he held similar views to those of Galileo. Galileo's arrest has more characteristics of politics than conflict between religion and science. There have been a number of suggestions as to what those factors may have been (an insult to the Pope, conflict between the Pope and the Duke of Tuscany, etc.), but none yet definitive.

Condition:Spine ends worn to text block. Lower corners slightly worn. A bit of a bend to upper board about 1/3 of the way from the spine. Page edges moderately toned. Scattered foxing and damp stains (as most volumes acquire in 450 years!). Accompanying images illustrate range of condition.

There is a large water stain in second part covering most of the pages 5-8; 13-16; 21-24; 29-32; 37-40. The stains get lighter, although they cover nearly the same area of the leaves (i.e. same spill). It would appear that the spill happened while the pages were stacked at the printer's/binder's since the intervening leaves do not have the water stain.

Three small holes appear to be imperfections in the paper: page 37/38, only affecting a couple letters; through the numbers on 319/320; and in margin of plate after first dialogue. The last couple of leaves are nearly separated, but are present. The only pages that appear to be missing are a half-title(?) and the errata to the first part.
